Dometic 385230980 OEM Toilet Bellows Pump for S and J Series Vacuum Pumps and T Series Discharge Pumps | White 9.09 x 5.39 x 4.09 inches

It works as expected. Easy job to replace. Gaskets don’t come with so order those as well. I ordered O-rings from Amazon when I ordered this bellows and O-rings never arrived. Had to get from local boat shop. Anyhow, this worlds great.

Came in a timely manner, product was good quality, no issue with install and working great in my Fleetwood Class A RV ... Looking to purchase another as a spare, but currently unavailable...

Original billows pump LEAKED brown stuff into bilge = BIG MESS !! The plastic billows actually split which allowed "STUFF" to escape pass the billows upward and out of the pump housing and into the bilge. The duckbill rubber valves are replaced routinely every 3 years. From now on, the billows will be replaced then also. Somewhat expensive, but WHAT A MESS. Remove pump from boat to service. Muriatic acid works best to "clean" pump housing & etc. Wear eye protection and rubber gloves with muriatic acid. When installing the duckbill valves, orient them in vertical position. If they are horizontal, the lower lip of the valve seems to "sag" prematurely, necessitating early replacement. Flush 2 full bowls of water with sudsy dish soap through system whenever leaving boat for more than a few days to prevent more frequent repairs and keep hoses clear of smelly "stuff".

Direct replacement for old part. Originally purchased a cheaper product that was faulty out of the box. This one works great so far.

Original Dometic bellow. OME part, Fitted well, better price than local marine store or online. Came in with the bolt, not the O rings.

Worked 1st time after installation as advertised.

Do NOT use chyneec knocks offs. This product has lasted for awhile thus far. Not this particular one, but another I had purchased earlier. I tried the alternatives, and you will be replacing it again in a fraction of the time you would be using this product.

I have the systems for 13 years and last Oct. I rebuilt them both for the first time..... the first one lasted 3 months and the bellow failed. thinking I did something wrong installing it, I just replaced it.... 2 months later the second one failed. They must have had a bad batch of pump bellows as both failed where the bellows connect to the piston. hopefully this fixed the problem. Note: after the rebuild the system is quieter and pumps faster. Update: failed again…. Ordered new one and tested before installing and the new one was bad out of the box…. I up it on the table and filled the center with water … it leaked out the bottom….

Schon nach kurzer Zeit defekt. Ganz schlechte Qualität

perfect, do wish they would include a couple of o'rings for when you replace this though !

I just installed this item and it works. Time will tell if it lasts over time. The price for this item (I believe I paid $ 158.00) is very high so I recommend that you shop around. I recommend that you buy the top grade part made by Dometic since it is a big job to install and you do not want a generic equivalent that may wear out sooner. Good Luck !!

Todo me gusto preciony tiempo
